ROAD-SCRAPER AND STONE-REMOVEB.

Application filed October 11, 1916.

To all whom it may concern:

Be it known that I, FRITZ E. Yomga citizen of the United States, residing at lCarlville, in the county of Madison and State of New York, have invented certain ne Y and useful Improvements in Road- Scrapers and Stone-Removers, of which the following is specification, reference being had to the accompanying drawings.

This invention relates to an improved road scraper and has for its primary object to provide a very simple and efficient device for scraping the road surface and eliminating irregularities therein and also collecting or gathering loose stone, the device being so constructed as to direct the earth to one side of the road while the stones are directed t0- ward the opposite side thereof.

It is a more particular objectof the invention to provide a device for the above purpose including a plurality of sectional scrapers hingedly connected for relative vertical movement, said scrapers being 0bliquely disposed across the road surface, and a plurality of toothed stone gathering rakes or combs flexibly connected to the sectional scraper and disposed obliquely across the road surface in a relatively pposite direction with respect to the scraper.

It is a further object of the invention to provide a road scraper which consists of relatively few parts of very simple construction so that the device is not liable to get out of order, and may be manufactured at relatively small cost.

\Vith the above and other objects in view, my invention consists in the novel features of construction, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which,

Figure 1 is a top plan view of a road scraper constructed in accordance with the preferred embodiment of the invention; and

Fig. 2 is a longitudinal section thereof.

Referring in detail to the drawing, 5 designates a series of platform sections. These sections are arranged in pairs disposed in the same plane, the sections in each pair overlapping upon the longitudinal edges of the next adjacent platform sections. The sections in the front and rear pairs are hingedly connected to each other, as at 6, and the overlapping edges of said platform sections are securely fixed to each other. The central pair of sections 5 are not hing Specification of Letters Patent.

edly connected but their inner opposed ends may move freely with respect to each other in the relative vertical movement of the hingedly connected sections of the platform. I I

To the forward longltudmal edge of each of the platform sections 5, a steel scraping strip 7 is secured.

To the ends of the rear scraper sections 5, the rearwardly extending bars 3 and 9 of relatively different lengths, are fixed. These bars, at their rear ends, are connected to each other by means of a series of slats 10, said slats being connected by hinges 11. By the provision of the bars 8 and 9 of ditl'erent lengths, the series of slats 10 are positioned obliquely with respect to the platform sections. The ends of a pair of chains 12 are loosely attached to the rear platform sections 5 and to the bar 9. These chains drag upon the road surface in the travel of the machine and collect the larger loose stones lying upon the road surface.

Rearwardly of the series of hingedly connected slats 10 and in parallel relation thereto, a series of rakes 13 are arranged, said rakes being disposed in overlapping relation and spaced from each other longitudinally of the machine, the left hand end of the rear rakes each being loosely connected by bolts 14 to the adjacent rake at the approximate center of the latter. The right hand ends' of the forward rakes are connected by short lengths of chains 15 to the next rake in the rear. In this manner, the several rakes are flexibly connected. A relatively large rake 17 is disposed rearwardly of the series of short rakes 13 in spaced relation thereto and is connected by means of the bars 18 to the two rear rakes 13. The ends of the bars 18 extend beneath the respective rake bars 13 and 17. Obliquely disposed brace rods 16 connect the rear ends of the bars 18 to certain of the rakes 13. The bars 18 have scraping engagement with the ground surface and direct the stones which escape the rake 13 toward the center of the road. The

teeth of the rakes 13 are vertically disposed,

while the rake 17 preferably has its teeth rearwardly curved, as shown. Chains or cables 19 are connected to the rakes 13 and to the rear edge of the scraper platform.- It will be understood that any suitable draft attachments may be provided on the forward edge of the scraper platform for connecting the draft animals thereto.

In the operation of the machine, as the same is drawn over the road, indicated in dotted lines in Fig. 1, the blades or strips 7 extending obliquely across the roadway. As

the platform sections are flexiblyconnected,

they may move relative to each other and thus enter rats or depressions in the road surface. The loose chains 12 direct the large rocks or stones toward'the right hand side of the road. The smaller stones are colflected by the several rakes 13, and such stories as may pass over these rakes or escape the same will be gathered by the rake 17. The rakes 1'3 and 17 also discharge the larger I stones collected thereby toward the right hand side of the road. The very small stones and the remaining loose earth being directed bythe bars 18 toward the center of .the road, is separately gathered or collected, as it may be desiredto use the finer material for use in makingrepairs or other.

purposes. Thus, it will be seen that the loose dirtor earth scraped from the road surface stones are discharged in is discharged in one direction while the an opposite direction so that the latter may be readily gathered. It will, therefore, be apparent that my improved road scraper is very serviceable and convenient in practical use and provides means for quickly and smoothly leveling the road surface.

. several advantages of the device will 'be fully --From the foregoing description, taken in connection wlth the accompanying drawmg, the construction, manner of operatlon and understood. The several parts-ofthe machine are exceedingly simple and durable in construction and highly efficient and reliable in operation. The machine may, of

' v. course,be manufactured in various sizes and at-relatively small cost. 7

While I have shown and described the preferred construction and arrangement of the severalparts, it is to be understood that the deviceis susceptible of considerable modification therein and I, therefore, reserve the privilege of adopting all such legitimate changes as may be fairly embodied within .the spirit and scope of the invention as claimed, 7 Having thus fully described my invention, what I desire to claim and secure by Letl ers Patent is 1. In a road scraper, a plurality of spaced, parallel, scraping members adapted to extend obliquely across the road surface to scrape the top soil therefrom and direct the .of the road.

2. In a road scraper, a plurality of spaced,

parallel, scraping members adapted to extend obliquely across the road surface to scrape the top soil therefrom and direct the sametoward one side of the road, a series of spaced, parallel, stone rakes arranged rearwardly of the scrapers to extend obliquely across the road surface in an opposite direction to the scrapers and direct the stones toward the opposite side of the road, and means flexibly connecting the rakes to each other and to the scrapers. 3. In a road scraper, a plurality of spaced parallel scraping members adapted to extend obliquely across the road surface to scrape the top soil therefrom and direct the same toward one side of the road, a series of spaced, parallel, stone rakes arranged rearwardly of the scrapers to extend obliquely across the road surface in an opposite direction to the scrapers and direct the stones toward the opposite side of the read, an additional rake disposed rearwardly of said series of rakes and in parallel relation thereto, and means flexibly connecting the stone rakes to the scrapers.

4:. In a road scraper, a series of platform sections flexibly connected for relative vertical movement, a metal scraping bar fixed to the forward edge of each of the platform sections, rearwardly extending bars of relatively different lengths fixed to the rear sections of the platform, a series of hingedly connected slats connecting said bars, said platform sections being obliquely disposed to the line of travel whereby the soil is directed by the scraper bars toward one side of the road, a series of flexibly connected rakes disposed rearwardly of said hingedly connected slats and obliquely across the road FRITZ E.
